A first sealing rubber gasket is arranged between the atomizer cover 114 and the cartridge 111, and a second sealing rubber gasket is arranged between the atomizer cover 114 and the air flowing pipe 112. The cartridge 111, the air flowing pipe 112, the sealing unit 113, and the atomizer cover 114 cooperate with each other to form a housing with the liquid reservoir chamber 115. A liquid injection channel 1131 is defined in the sealing unit 113, such that liquid solution can be injected into the liquid reservoir chamber 115 through the liquid injection channel 1131. A liquid outlet 1141 is defined in the atomizer cover 114, thus, the liquid solution can flow out of the liquid reservoir chamber 115 through the liquid outlet 1141. In other embodiments, the liquid injection channel 1131 can be defined in the cartridge 111 or other components of the atomizer device 10; and the sealing unit 113, the cartridge 111, and the air flowing pipe 112 can be integrally formed, thus, the sealing unit 113 forms an end wall of the liquid reservoir chamber 115.

Referring to FIGS. 4, 7, and 8, the suction nozzle assembly 12 includes a suction nozzle 121, a fixing member 122, and a first adjusting ring 123. The fixing member 122 is arranged between the suction nozzle 121 and the sealing unit 113. The suction nozzle 121, the fixing member 122, and the air flowing pipe 112 communicate with each other. The fixing member 122 includes a cylindrical body 1221 and an annular abutting portion 1222 arranged on an outer wall of the cylindrical body 1221. The abutting portion 1222 abuts the adjusting valve 13 against the sealing unit 113.

In some embodiments, the adjusting valve 13 includes an annular adjusting cover 131. The adjusting cover 131 is rotatably sleeved on the cylindrical body 1221, and is located between the sealing unit 113 and the abutting portion 1222, correspondingly engaging with the sealing unit 113. The adjusting cover 131 contacts the sealing unit 113, and is capable of rotating between a first position and a second position across a surface of the sealing unit 113. A first opening 1311 is defined in the adjusting cover 131. In some embodiments, the adjusting cover 131 may include a rotating ring 1312 arranged on an outer ring of the adjusting cover 131; anti-skid designs may be provided on an outer wall of the rotating ring 1312, thus, an external force may be applied to the rotating ring 1312 to rotate the adjusting cover 131. In other embodiments, the adjusting cover 131 may be located on an inner wall of the liquid reservoir chamber 115 to engage with an inner wall of the sealing unit 113, and the adjusting cover 131 may be driven to rotate by other means.

When the adjusting cover 131 is in the first position, the first opening 1311 communicates with the liquid injection channel 1131 to open the liquid injection channel 1131; when the adjusting cover 131 is in the second position, the first opening 1311 misaligns with the liquid injection channel 1131 to close the liquid injection channel 1131.

A first adjusting opening 1231 is defined in the first adjusting ring 123, corresponding to the first air inlet 1223. When the first adjusting ring 123 is rotated, the first adjusting opening 1231 adjusts an area of an opening of the first air inlet 1223 which communicates with atmosphere, thus, the amount of air flowing into the suction nozzle 121 can be adjusted and thus the temperature of the smoke at the suction nozzle 121 can be correspondingly adjusted. A restricting portion 1224 is arranged on the side wall of the cylindrical body 1221, and a restricting slot 1232 corresponding to the restricting portion 1224 is defined in the first adjusting ring 123.

In some embodiments, the sealing unit 113 includes a sealing cover 113 a, a fastening member 132, and a sealing plug 1133. The sealing cover 113 a is made of flexible rubber such as silicone. A second opening of the liquid injection channel 1131 is defined in the sealing cover 113 a. A sealing ring 1134 protrudes from a surface of the sealing cover 113 a, corresponding to the adjusting cover 131. The sealing ring 1134 forms an enclosed structure around the second opening, being capable of preventing the leakage of the liquid solution through a gap between the sealing cover 113 a and the adjusting cover 131. In addition, the sealing ring 1134 reduces the contacting area between the adjusting cover 131 and the sealing cover 113 a, thereby facilitating the rotation of the adjusting cover 131.

In some embodiments, the fastening member 1132 includes an annular plate 1135, a first sleeving portion 1136 arranged in an inner ring of the plate 1135, and a second sleeving portion 1137 arranged on an outer ring of the plate 1135. The first sleeving portion 1136 engages with an inner wall of the corresponding end of the air flowing pipe 112 and the second sleeving portion 1137 engages with an outer wall of the corresponding end of the cartridge 111, thus, the sealing unit 113 can be fastened to the cartridge 111 and the air flowing pipe 112. The cylindrical body 1221 engages with the inner ring of the plate 1135 to communicate with the air flowing pipe 112, thus, smoke can flow through the cylindrical body 1221.

In some embodiments, the sealing plug 1133 is also made of flexible rubber such as silicone. The sealing plug 1133 seals a gap between an outer wall of the air flowing pipe 112 and an inner wall of cartridge 111, and the plate 1135 is located between the sealing cover 113 a and the sealing plug 1133. A third opening and a fourth opening of the liquid injection channel 1131 are defined in the plate 1135 and the sealing plug 1133, respectively.

In some embodiments, a protruding portion is arranged on the sealing plug 1133, extending towards the plate 1135. A first positioning hole is defined in the plate 1135, corresponding to the protruding portion. The protruding portion is clamped into the first positioning hole, thereby enabling the circumferential positioning of the sealing plug 1133 and the fastening member 1132. An extending portion is arranged on an outer ring of the second opening and extends towards the plate 1135. A first recessed portion corresponding to the extending portion is formed on an outer ring of the third opening. The extending portion engages with the first recessed portion to enable the circumferential positioning of the sealing plug 1133 and the fastening member 1132.

Referring to FIGS. 5, 7, and 9, the atomizer base 14 engages with the atomizer cover 114, and the atomizer assembly 15 is located between the atomizer base 14 and the atomizer cover 114. The atomizer assembly 15 includes a cylindrical heating coil 151 made of ceramics. An inner hole of the heating coil 151 communicates with the air flowing pipe 112. A through hole 141 communicating with the inner hole of the heating coil 151 is defined in a middle portion of the atomizer base 14, such that air flow can flow into the inner hole of the heating coil 151.

In some embodiments, two silicone covers 152 are arranged on outer rings of the two opposite ends of the heating coil 151 respectively, such that a middle portion of the heating coil 151 forms a liquid absorbing portion 1511 which absorbs the liquid solution flowing out through the liquid outlet 1141. The heating coil 151 is heated after conducted to the battery device to atomize the liquid solution. The smoke flows towards the suction nozzle 121 through the air flowing pipe 112.

The silicone covers 152 perform a sealing function between the corresponding end of the heating coil 152 and the atomizer cover 114/the atomizer base 14, preventing the leakage of the liquid solution through the inner hole of the heating coil 152. In addition, the arranged position of the silicone cover 152 can be adjusted to control the amount of the liquid solution flowing into the heating coil 152, which prevents too much liquid solution from flowing into the heating coil 152. Thus, leakage of the liquid solution caused by incomplete atomization of the liquid solution can be avoided.

In some embodiments, the cartridge 111, the air flowing pipe 112, and the atomizer cover 114 are made of ceramics. Thus, before the liquid solution injected into the electronic cigarette gets heated by the heating coil 151, the liquid solution only contacts the components of the electronic cigarette which are made of ceramics and silicone rather than metal or plastic. Thus, the situation that harmful ingredients from metal or plastic affect the user's health can be avoided.

Referring to FIGS. 5, 7, and 10, the air inlet assembly 16 is arranged on one end of the atomizer device 10 opposite to the sealing unit 113. The air inlet assembly 16 communicates with the air flowing pipe 112. The air inlet assembly 16 includes an air inlet tube 161 and a second adjusting ring 162 rotatably arranged on an outer ring of the air inlet tube 161. The air inlet tube 161 engages with the atomizer base 14, such that the air inlet tube 161 can communicate with the through hole 141 of the atomizer base 14. In other embodiments, the air inlet tube 161 can directly communicate with the inner hole of the heating coil 151.

In some embodiments, an air inlet hole unit 163 is formed in a circumference of the air inlet tube 161, allowing air to flow into the air inlet tube 161. The air inlet tube 161 engages with the atomizer base 14, such that the air flowing into the air inlet tube 161 can flow into the inner hole of the heating coil 151.

A second adjusting opening 1621 is defined in the second adjusting ring 162, corresponding to the air inlet hole unit 163. The rotation of the second adjusting ring 162 adjusts an area of a portion of the air inlet hole unit 163 which allowing air to flow into the air inlet tube 161, thus, the amount of air flowing into the electronic cigarette and the amount of the smoke sucked by a user of the electronic cigarette can be adjusted.

Referring to FIG. 10, in some embodiments, the air inlet unit 163 includes a plurality of second air inlets 1631 arranged on the circumference of the air inlet tube 161. The air inlets 1631 are of different areas. An area of the second adjusting opening 1621 is no less than that of the largest second air inlet 1631. The rotation of the second adjusting ring 162 enables the second adjusting opening 1621 to communicate with different second air inlets 1631 of different areas respectively, thus, air can flow into the air inlet tube 161 through the corresponding second air inlet 1631 to enable the adjusting of the amount of air flowing into the electronic cigarette.

Referring to FIG. 11, in other embodiments, the air inlet unit 163 can include a number of third air inlets 1632 arranged on the circumference of the air inlet tube 161. A second recessed portion 1622 is formed on an inner wall of the second adjusting ring 162, and the second recessed portion 1622 extends to an end surface of the second adjusting ring 162. Two boundaries of the second recessed portion 1622 in the circumferential direction of the second adjusting ring 162 respectively correspond to two end boundaries of the third air inlets 1632 in the circumferential direction of the air inlet tube 161. The second adjusting valve 162 can be rotated to adjust an area of a portion of the third air inlets 1632 communicating with the second recessed portion 1622. For example, the second adjusting ring 162 can be rotated to different positions such that air can flow into the atomizer device through the corresponding third air inlet 1632 communicating with the second recessed portion 1622, thus, the amount of air flowing into the air inlet tube 161 can be adjusted.

Referring to FIGS. 10 and 11, in order to ensure the accuracy of the rotating position of the second adjusting valve 162 and ensure the positioning of the second adjusting valve 162 after the second adjusting valve 162 is rotated, an elastic column 164 is arranged on the outer wall of the air inlet tube 161, and a number of clamping mechanisms 1623 engageable with the elastic column 164 are formed in an inner ring of the second adjusting ring 162 along a circumference of the second adjusting valve 162. The elastic column 164 engages with the corresponding clamping mechanism 1623, thereby enabling the positioning of the second adjusting ring 162.

Referring to FIGS. 12 and 13, in other embodiments, the suction nozzle 121 can be clamped to the adjusting valve 13, and the adjusting valve 13 can be driven to rotate between the first position and the second position by the suction nozzle 121. For example, the adjusting valve 13 may include the adjusting cover 131 and the sealing cover 113 a located between the adjusting cover 131 and the sealing unit 113; a first protrusion is arranged on the sealing cover 113 a, and a second positioning hole is defined in the adjusting cover 131, corresponding to the first protrusion; and the first protrusion engages with the second positioning hole to enable the circumferential positioning of the sealing cover 113 a and the adjusting cover 131.

The rotation of the suction nozzle 121 drives the adjusting cover 131 and the sealing cover 113 a to simultaneously rotate between the first position and the second position. The first opening 1311 penetrates the adjusting cover 131 and the sealing cover 113 a and corresponds to the liquid injection channel 1131 of the sealing unit 113. When the adjusting valve 13 is in the first position, the first opening 1311 communicates with the liquid injection channel 1131, thus, the liquid injection channel 1131 is opened; when the adjusting valve 13 is in the second position, the first opening 1311 misaligns with the liquid injection channel 1131, thus, the liquid injection channel 1131 is closed.

In some embodiments, a second protrusion is arranged on the suction nozzle 121 and a clamping slot is correspondingly defined in the adjusting cover, and the second protrusion can be clamped into the clamping slot to enable the circumferential positioning of the suction nozzle 121 and the adjusting cover 131. The suction nozzle 121 is capable of moving back and forth along an axial direction to be clamped into the adjusting cover 131 or to disengage from the adjusting cover 131. When liquid injection is required, the suction nozzle 121 is pushed inwards to engage with the adjusting cover 131 and thus drives the adjusting valve 13 to rotate to the first position to open the liquid injection channel 1131. After the liquid injection is finished, the suction nozzle 121 is rotated to drive the adjusting valve 13 to rotate to the second position, and then the suction nozzle 121 is slid outwards to disengage from the adjusting cover 131. An elastic member 124 is arranged between the suction nozzle 121 and the adjusting cover 131. The elastic member 124 is configured to provide an elasticity to keep the suction nozzle 121 from disengaging from the adjusting cover 131, thus, mis-opening of the liquid injection channel 1131 caused by mis-rotation of the adjusting cover 131/the suction nozzle 121 can be avoided.
